Reflects upon the nature of theory-driven computer assisted second language learning (CALL), particularly as it relates to the courseware development process. The study examines the implications for theory-driven CALL as well as the concept of "fit" between the theoretical framework or pedagogy and the computer's capabilities. The study addresses…

Contributes to a reflection on the possibilities and the limits of a non-naive use of the history of mathematics for educational purposes. Discusses a problem related to the hypotheses that make it possible to confront past and modern conceptual developments. Contains 45 references. (DDR)

Reports results from a close study of five classes that are learning National Curriculum science with the help of special materials. Contains excerpts from interviews and test scores that illustrate some of the problems students have in understanding the nature of experiment and theory. (DDR)

Suggests that thematic roles might best be viewed as verb-specific concepts and that this conceptual/world knowledge is computed and used immediately in online language processing. Discusses results in relation to other recent treatments of thematic roles as well as constraint-based and garden path models. (68 references) (Author/CK)

Presents a framework for assessing probabilistic thinking based on validated data obtained from eight third grade children who served as case studies. Major constructs were sample space, probability of an event, probability comparisons, and conditional probability. Levels of thinking appear to agree with the levels of cognitive functioning…

Describes a study of the estimation skills of mathematicians (N=44), accountants (N=44), psychology students (N=44), and English students (N=44). Explores their methods of estimating the products and quotients of 20 problems. Contains 49 references. (DDR)

Discusses how important it is for teachers to be open to alternative procedures and strategies that students may use. Suggests that a method that is meaningful rather than one learned by rote will help students develop more confidence and understanding. (KHR)

Undergraduates (n=195) were asked to work on three creative problem-solving tasks. Beliefs consistent with the nature of the task were found to be those most likely to be related to performance. Belief measures were found to be reasonably powerful predictors of the production of original, high-quality solutions. (Contains references.) (CR)

Characterizes students' understanding of the rock cycle system. Examines effects of a knowledge integration activity on their system thinking. Interprets answers to an open-ended test using a systems thinking continuum ranging from a completely static view of the system to an understanding of the system's cyclic nature. Reports meaningful…

Considers educational aspects of the development of ratio and proportion focusing on the arithmetization undergone by these concepts in light of the relationship between mathematics and music. Investigates the instructional aspects of compounding ratios. Points out features of the differences between identity and proportion which can be…

Explores teaching methods to improve students' understanding of quantitative chemistry and their ability to solve related problems using the Multidimensional Analysis System (MAS). Investigates the relationships between MAS-classified chemistry problems and student achievement in solving these problems. Shows that improvement in student…

Investigates the depth and accuracy of 6th grade students' content understandings as well as the use of search-and-assess strategies when using on-line resources. Uses scaffolded curriculum materials while completing on-line inquiry units. Concludes that students develop accurate and in-depth understandings if they use search-and-assess strategies…

Explains the place of science process skills in a quality science program. Introduces activities for the basic and integrated science skills that will lead to an understanding of the basic element of scientific literacy. Describes definitions, activities, and assessment techniques for developing interpreting data, controlling variables,…

Reports research that examines children's models of seed. Explores the conceptions held by children (N=75) of germination and seed formation. Concludes that children hold a restricted meaning for the term 'seed'. (DDR)

Identifies certain conceptions regarding the science content studied by students aged 9-11 years and develops a strategy for altering these conceptions. Reviews research on misconceptions and defines action research. (DDR)
